LEASING MECHANISM SPECIFICATION forming part of Letters Patent No.438,563, dated October 14, 1890.

Application filed February 10, 1890.

To all whom it may concern.-

Be it known that I, JosEPH Mo. SIMONEAU,

a citizen of the United States, residing at Ware, in the county ofHampshire and State of Massachusetts, have invented new and usefulImprovements in Leasing Mechanism for Warp-Dressers, of which thefollowing is a specification.

This invention relates to improved devices or mechanism used inconjunction with a warp-dressing machine or slasher for securing a leaseor decussative arrangement of the warp threads or yarns before the samepass through the dressing rolls or slasher, so that by the insertion ofproper lease-retaining cords or rods, which may pass through the dresseror slasher with the yarn, when the leased section of the warp-yarns hascome near to the warp-beam it may be cut,leaving the yarn in two equalseparated portions, the

yarns of the one portion alternating and still retaining their X-likerelations, so that when the said yarns are taken on the warp-beam to theloom they may be due to their leased condition readily run in throughthe harnesses by the running-in hand.

The object of this invention is to provide a device or mechanism whichhas advantages as follows: First, it is of simple construction and ofeasy operation; secondly, it possesses a capacity for manipulating andcontrolling a number of yarns largely in access of What I have hithertounderstood to be customary and possible in leasing devices, and,thirdly, the mechanism is so equipped in relation to the set ofsection-rolls in conjunction with which it operates and with the slasheror dresser that it may be readily removed with said section-rolls fromits proximity to thezslasher or dresser, whereby a new set ofsection-rolls and a similar leasing device therefor may be substituted,so that new work may be immediately brought to the slasher,necessitatingno delay or loss of time by the latter; and the inventionconsists in the construction and combination of parts, all substantiallyas will hereinafter more fully appear, and be set forth in the claims.

In the accompanying drawings, Figure 1 is Serial No. 389,929. (Nomodel.)

a side elevation and partial vertical section of a set of section-rolls,the lease-forming devices, and a part of the dresser or slasher. Fig. 2is a plan view of a portion of the removable lease-forming devices. Fig.3 is a vertical cross-section on line 2 2, Fig. 1. Fig. 4 is a verticalcross-section on the line 3 3, Fig. 1, with both warp-beams inelevation. Fig. 5 is a detail view in illustration of an improvedconstruction of reed, which is advantageously adapted for use in thisleasing mech- 6o anism. Fig. 6 is a view in the nature of a diagramindicating an enlarged plan or horizontal cross-section of thereed-frames, showing the relations of the open spaces between certain ofthe reed-rods,with the yarn-engaging abutments between other of thereed-rods, and the relations of the yarns with each other and with saidopen reed-spaces, and with said spaces having yarn engaging abutments,shoulders, or blocks. Fig. 7 is a vertical sectional view along the runof the warp-yarns through the reeds, showing certain of said reeds as ina position occupied thereby in one part of their lease-formingmovements. Fig. 8 is a similar view to Fig. 7, showing another pair ofthe reeds as in the position occupied thereby in another part of thelease-forming operation. Figs. 9 and 10 show the manipulations of thelease-forming devices when the same comprise but two reed-frames.

In the drawings, A A represent a set of section or yarn supply rolls,mounted in suitable bearings of a removable frame B, said frame beingsupported upon or in proximity to a main frame D, which is alsoavailable for the reeds 1, 2, 3, and 4, said frame D being in proximityto or an extension of the frame of the dresser or slasher O, which maybe of any suitable construction and operated upon anyapproved'principle.

a 0 are guide-rolls for the yarn, one a between the section-rolls andthe reeds and the other 0 between the reeds and the slasher. The sizingapparatus of the slasher may be located between the said roll 0 and thelarge drum, partly shown at the extreme left of Fig. 1. I

All the reeds E, particular ones of which are designated by the numerals1, 2, 3, and 4, as to their positions, are mounted in a supplemental orreed frame F, which fits into openings of and is supported and steadiedby the common or extension frame D. Said reedframe comprises asupporting-bottom Z), and suitable side and end beams or walls d,in thesides of which are vertical gnideways j for the reeds 1, 2, 3, and 4.

In relation to the foot-rail of each reed is provided an elevatingdevice, here shown as consisting of vertical push-up rods g, which areengaged by levers 71, respectivelyprovided therefor, which levers aresuitably fulcrumed on and extended laterally outside of theextension-frame D for being readily swung. The reed swung up by theaction of the lever falls to the bottom of the reed-frame F by its owngravity.

Each reed consists of a rectangular frame, having between the upper andlower bars or rails thereof the series of vertical reed-rods 10, withspaces 12 between them, said spaces being usually intended to freelyadmit of the side-by-side disposition of at least three, and often more,threads or yarns, and the alternate spaces between the reed-rods areintermediately of their vertical extent divided by a suitable filling-inblock, cross-pin, or other suitable form of yarn-engaging abutment orshoulder 13, the essential, under whatever specific constructionemployed, being a reed having suitable alternating yarn-engagingabutments in given horizontal lines, substantially as shown, andrelatively intermediate open spaces which extend above and below saidline of yarn-engaging abntments.

The yarns from the section-rolls may be run in through the reeds in anysuitable manner, and in Fig. 6 the arrangement of the yarns relativelyto each other and to the engaging abutments of the reeds is illustrated.

Where four reeds are employed, each yarnabutment 13 thereof engagesevery fourth yarn. The next three yarns pass freely through the openreed-section next to said abutment, each of said three yarns beingengaged by an abutment of one of the other reeds, respectively,therefor. For instance, noting the view, Fig. 6, the yarn a has a freepassage through or non-engagement with reeds 1, 2, and 3, but is engagedwith the abutment of reed 4;. Yarn a has a free passage through reeds 1,2, and 4, and an engagement with reed 3. Yarn a has a free passagethrough reeds 1, 3, and t, engaging reed 2, and yarn a has an engagementwith reed l and a free passage through reeds 2, 3, and 4, the openreed-spaces through whichthree yarns of each set of four pass being in aplane next to but just one side of the reed, respectively, engaging thefourth yarn,.and then the successive yarns from the section-rolls arerun through the other reedspaces successively in red uplication of thearrangement already described, and it will be seen that by raising, say,reed 1, every fourth yarn will be raised, or by raising reeds 1 and 3every other yarn will be raised, or half of the yarn, leaving the otherhalf in horizontal lines, and where four reeds are employed to form thelease the operation may be carried out as follows, reference being hadto Figs. '7 and 8: Reeds 1 and 3 are lifted, carrying up half the yarns,which are the alternate ones of all the yarns run through the fourreeds, and a separator slide rod or strip j, having a suitable width orheight, is inserted in advance of all the reeds (and between them andthe foremost guide-roll 0) in the shed formed by the said half of theyarn and the other relatively intermediate half which has not beenraised, and then the reeds 1 and 3 are permitted to drop to theirlowermost position, leaving the yarns which had been raised therebystill forming a slight shed or one of small height extending from thetop of said separatorslide back to the rear guide-roll a, and thisposition of said yarns which had been raised is also indicated in saidFig. 7 by the dotted line 072, and also in Fig. Sbytheline m. Now, reeds2 and 4 are lifted, carrying up the other half of the yarns, (whichalternate with the said first-raised half,) as indicated by Fig. 8, anda decussation is formed by said yarns m, which extends under saidseparator-slide j in its course from the forward guide-roller andupwardly across the lower half of the yarns to the reed-abntments ofsaid reeds 2 and 4 with which said last-raised yarns respectivelyengage, and as these last-raised yarns cross the first manipulated yarnssomewhat in advance of reed 4 a separator-slide 7c is inserted in theshed next to the said reed 4:, and then when reeds 2 and t are alsodropped the discussative arrangement, which is substantially or whichconstitutes the lease, is still maintained, and by replacing the saidseparator-slides j and 7a by cords or other flexible separators the sorelatively-disposed parts may be run through the slasher or dresser andup near to the warp-beam, when the portions of the yarn to the rear ofboth of said separating-cords is severed, and the leased arrangement maythen, if desired, be the better secured by knotting or tying theseparated alternate ends, as usual.

hen the number of yarns to be leased is of such a low number that tworeeds only need be employed, the operation, as is obvious, issubstantially the same as has been described, it being understood thatthe two reeds under the conditions above set forth serve to carry thegreater number of yarns as the occasion hecessitates; but the movement-sof pairs in conjunction are to all intents and purposes the same as of asingle reed. Therefore, noting Figs. 9 and 10, wherein are shown reeds 1and 2, every other yarn-engaging reed 1 while the relativelyintermediate or alternate yarns are engaged by reed 2, on raising reed1, as shown in Fig. 9, half of the yarns are lifted, forming a shedbetween them and the lower half, and a separator-slide is inserted wellforward of reed 2, and reed 1 is ITO ' permitted to drop, there stillremaining a slight but sufficiently clearly-defined shed, as indicatedby the line m in Figs. 9 and 10. Then raising reed 2 the other half ofthe yarn is raised, forming the decussation or crossshed in advance ofreed 2 and between it and the first-inserted separator-slide, as clearlyindicated in Fig. 10, and the second separator inserted, as also shownin said Fig. 10.

It is plain that after a lease decussation has been formed in advance ofthe reeds in the manner already described by then similarly manipulatingthe reeds, forming sheds extending therefrom to the rear of said reeds,and by the proper insertion of separatorslides, another leasedecussation may be formed at the rear of the reeds. This lease will heoften found advantageous when it is desired to run in new or differentkinds of yarn from different section-rolls through the reeds, for bycutting the yarns at the rear of the said rear lease the ends of the newyarn may be readily spliced with or twisted upon the lease-forming endsof the yarns which still remain by a portion thereof through the reeds.This capability largely facilitates the work, for the running in of theends anew through the reeds is found to be much slower and more tediousthan twisting on or splicing the yarn-sections, which are already intheir proper relative engagements with the reeds.

In Fig. 5 I have illustrated an improved form of reed to be employed,which consists in forming the reeds alternately with open spacesthroughout their length and having the relatively intermediate spacesprovided with the middle abutments, as has been already mentioned, butforming the upper end of each reed-rod with a shoulder or angularprojection 14, which extends toward and to a contact with the nextadjacent reed-rod, but which is not confined to said next adjacentreed-rod. The top of each reed-rod shoulder inclines downwardly acrossthe Width of said shoulder, meeting the face of the next adjacentreed-rod somewhat below its upper end. Therefore in running in the yarnsbet-ween the reed-rods, instead of hooking them through the spacesintermediately of the length of the reed, the yarns are carried inbetween the ends of the reed-rods,which may spring apart sufficiently topermit of their entrance, the said inclined top surfaces of thereed-rods and their shoulders permitting the easier and more conveniententrance of the yarns, and the said shoulders serve to maintain theproper separation of the rods the one from the other, maintaining themall uniformly and preventing their collapsing or binding upon the yarn.It is preferred to employ a removable cap n to cover or inclose theupper ends of the reed-rods, and also to steady and render more rigidthe reed in its entirety.

From theconstruction indicated in the drawin gs, Figs. 1 and 3, it willbe readily seen that the reed-holding frame F may be, with the reedstherein, bodily removed from the comalso combined therewith a series oflease-forming reeds and reed-carrying frame. The reedcarrying frame andthe section-roll supports are independently removable, so that byforming a lease between the reeds and the sectionrolls and severing theyarns at the rear of the lease on removing the section-rolls andreplacing the same by other section-rolls, as some occasions mayrequire, and twisting the ends of the new yarns onto the ends of theleased yarns in the reeds the work may be proceeded with as before, itbeing unnecessary under this method of procedure to equip with every setof section-rolls a separate set of lease-forming reeds, although usuallyit is intended so to do, as by this plan the slasher or dresser may bekept constantly at work, it of course being understood that the slasheror dresser consists of a mechanism of much greater expense than theleasing devices, it at the same time having a capacity for dressingperhaps all the yarn which might be supplied to it from all thesection-rolls in the factory, however great their number may be. It istherefore deemed expedient to keep the dresser or slasher always atwork, and it is the aim in the preparation of the yarn at the slasher ordresser to avoid long waits at the times of preparing to run through newseries of yarns.

What I claim as my invention is 1. The combination, with a slasher ordresser provided with an extension-frame, of a set of reeds, each reedof the set comprising a series of reed-rods having spaces and abutmentsin the arrangement above specified, and a carrying-frame for said reedshaving guideways in which said reeds are vertically movable, saidreed-frame being removablysupported on said extension-frame of theslasher, and a bearingsupport for section-rolls, which is also adaptedto be removably connected to and supported by said extension-frame, forthe purpose set forth.

2. The combination,with a slasher or dresser provided with anextension-frame, of a reedguiding frame which has at its opposing sidesvertical ways and at its bottom vertically-movable and independentreed-supports, a set of reeds, each reed thereof comprising a series ofreed-rods having spaces and abutments in the arrangement specified andresting on said supports and constrained to move in said vertical ways,and a separate lever for each reed-support fulcrumed on saidextension-frame and having an engagement with its respectivereedsupport, all whereby each reed maybe raised and loweredindependently of another, for the purpose set forth.

3. In a lease-forming mechanism, substantially as described, a set ofreeds, each of which comprises aseries of reed-rods suitably supportedon an outer frame, which rods are spaced or separated from each otherand open to their top ends, whereby entrance to said spaces may be hadthereat, and every reed-rod having at its upper end an extension orshoulder 14, projecting against but unsecured to the next adjacentreed-rod, the alternate spaces in each reed being provided intermediateof the lengths thereof and below the said shoulders with yarn-engagingabutments, and the relatively intermediate spaces being free orunobstructed with respect to their middle portions and below saidshoulders, for the purpose set forth.

4. In a lease-forming mechanism, substantially as described, a set ofreeds, each of which comprises a series of reed-rods suitably supportedon an outer frame, which rods are spaced or separated from each otherand tively intermediate spaces being free or unobstructed with respectto their middle portions, and the movable cap n for covering andsteadying the upper extremities of the said reed-rods, for the purposeset forth.
